Tracking particles created in subatomic smashups takes precision. So before the components that make up detectors at colliders like the Relativistic Heavy Ion Collider (RHIC) get the chance to see a single collision, physicists want to be sure they are up to the task. A group of physicists and students hoping to one day build a new detector at RHIC—a DOE Office of Science User Facility for nuclear physics research at the U.S. Department of Energy’s Brookhaven National Laboratory—recently spent time at DOE’s Fermi National Accelerator Laboratory putting key particle-tracking components to the test.

Scientists at Brookhaven National Laboratory will work to understand the emergent properties of the superhot primordial soup called "quark-gluon plasma" (QGP), generated at the Relativistic Heavy Ion Collider (RHIC). QGP's perfect fluidity and other collective properties are a mystery.To address that mystery, a group of nuclear physicists has formed a new scientific collaboration that will expand on discoveries made by RHIC’s existing STAR and PHENIX research groups. This new collaboration, made up of veterans of the field and researchers just beginning their careers, has precise ideas about the measurements its members would like to make—and hopes of upgrading the PHENIX detector to make those measurements at RHIC.
